MAXIMINE is a compiled, comprehensive, spreadsheet-based, macro- driven software package, written to aid in the rapid and early assessment and design of virtually any small, medium, and large mining or quarrying project. The system has been des

Powered support plays a major role in longwall mining and improper selection may lead to a disaster. While different countries follow different norms, a universal approach is needed to be developed. For this purpose, a computer program C-ALPS

Proton microprobe analyses of trace elements have been carried out on a wide variety of ilmenites, garnets and chromites, to improve diamond exploration methods. The results so far show the potential to discriminate between barren and diamondiferous source rocks, and to distinguish multiple sources within single Drainages.

The international scientific and engineer-ing community is being challenged to take advantage of the opportunity offered by the U.N. International Decade for Natural Disaster Reduction (IDNDR) program to reduce rapid onset geological hazards along the Pacific Rim. Natural disasters observe no national boundaries; international cooperation offers the best opportunity to reduce the losses these catastrophic events create.

The geologists at the Zinc Mine in Broken Hill have developed a method of logging core using portable MS-DOS computers and LOTUS 123. The computer based logging system has almost halved both the time and cost to produce a completed log. The system is fast, flexible, easy and pleasant to use.

It is extraordinary that while Australia depends heavily on mineral wealth for its economic well-being, most Australians have no appreciation of the traditions and principles which drive and govern the mineral industry. Their understanding has been largely provided by those who campaign against the industry in one way or another and is therefore quite unrepresentative.

The law relating to the Treaty of Waitangi is developing rapidly at present. A number of separate, but related, developments can be identified.

The origins of instrument application in the Mineral Industry are discussed. Development of measurement techniques pertinent to the industry is described as is the early application of mini-computers. The current application of microprocessor based equipment and the benefits obtained from this range of equipment are discussed. A speculative opinion as to what future instrument development may offer the industry is outlined.

Aspects and anomalies in the present Standard Specifications for Blended Cements which may have operated in Australia against the development of the greater use of Slag Blended Cements are noted. Estimates of slag and ash usage in Australia are given and the need for further research with local materials stressed.

The new field of environmental investiga tions introduces new problems of ethics, res- ponsibility, conflict of interest and technical procedures. Such investigations involve four elements: developer, consultant, approving authority and the public. It is essential that the consultant provide technical competence, speed and efficiency, impartiality and credibi- lity. Despite allegations to the contrary, it is not in the consultant's own best interest to omit, ignore or obscure significant adverse en vironmental impacts.

In the 25 years since Broken Hill's 75th Anniversary which was marked by an Australasian Institute and Mining and Metallurgy Conference in Broken hill, there have been some significant changes in the role of mines inspectors. This paper updates the information given by the then Chief Inspector of Mines, J.H. Burford, to that 1968 Conference, with an emphasis being placed on mines inspection, although it also reflects changes to mining legislation and regulatory bodies.

A schematic overview of the variables which interact to determine ore reserves precedes consideration, in this context, of some recent views on the concept of a 'production cycle'. Political and governmental action, for whatever motives, is a greater obstacle to future mineral supply than technical problems.

Dr David Dekker discussed the importance of a multidisciplinary approach to automation, the infrastructure required to support automation, and selecting the equipment for automation. Dekker stressed that automation involves a number of technologies. The mining industry is currently about part-way through the evolutionary process of achieving a fully integrated automation system. He pointed out that the final stages require parallel development of infrastructure such as mine communications. Technologies required for automation Automation systems consist of three parts: the gathering of information, the processing of that information, and taking action.

A/method of introducing nitrogen into alloy steels using iron and ferromanganese nitrides is considered. Data are I ded on the nitrides produced. The kinetics of the formation of the'nitride product from the reaction between or ferromanganese powder and ammonia are presented, together with an indication of the efficiency of the Reactions.
